This paper proposes a filter design for improving the control performance of the current control system of Permanent Magnet Synchronous Motors (PMSMs) using the overmodulation region of an inverter. The control performance of a vector control system for PMSMs using the overmodulation region of an inverter can be improved by suppressing harmonic components that are generated in this region. This paper utilizes Band Elimination Filter (BEF) to eliminate harmonic components; however, unsuitable BEF setting leads to generation of large current oscillation at the resonant frequency of current feedback loop with BEF. In order to deal with these problems, the proposed filter design focuses on gain setting at the cutoff frequency of BEF. The proposed filter design can prevent the generation of current oscillation at the resonant frequency of the system, and can improve current control performance without complex adjustments. Simulations and experiments are carried out to show the effectiveness of the proposed BEF setting.

High performance V/f control of PMSM using state feedback control based on n-t coordinate system 査読有り国際誌

Matsuki Y., Doki S.

IEEJ Transactions on Industry Applications 138 巻 ( 12 ) 頁： 911 - 919 2018年

担当区分：最終著者記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：IEEJ Transactions on Industry Applications

This paper proposes a new V/f control method for permanent magnetic synchronous motors (PMSMs) without a position sensor. The proposed method uses state feedback control based on an n-t coordinate system, and controls rotational speed and the voltage amplitude. The t-axis is a tangent line of a constant voltage ellipse, and the n-axis is a normal line of the ellipse. The t-axis current is utilized to place the poles of the transfer function at the desired position at low speed and high speed conditions. The effectiveness of the proposed method was verified by simulation and experimental results.

A dual-degrees of freedom based PWM for single phase three level rectifiers with a strong neutral point potential control ability 査読有り国際誌

Guan B., Doki S.

Proceedings IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society 2017-January 巻頁： 527 - 532 2017年12月

For the discussion about the neutral point potential (NPP) control of single phase three-level rectifiers, most of the methods solve the NPP problem by adjusting the zero-sequence voltage under symmetrical load conditions. However, when one phase voltage reaches to the maximum voltage, the other phase voltage goes to the minimal voltage. As a result, the NPP control ability is limited since there is no chosen zero-sequence voltage when the modulation ratio is close to 1. It can not be suitable for some strong asymmetrical load applications, in which two DC-link capacitors are used to drive different loads separately. In this paper, a dual-degrees of freedom based PWM is proposed, which can enhance the NPP control ability for single phase three level rectifiers. Introducing a new degree of freedom, the proposed method has more choices for the NPP control. It can decrease the NPP fluctuation under the strong asymmetrical load conditions, compared with the traditional PWM methods. The simulation results ratify the correctness and feasibility of the proposed PWM method finally.

Measuring position determination for accurate and efficient visual inspection using UAV 査読有り国際誌

Asa K., Funabora Y., Doki S., Doki K.

SII 2017 - 2017 IEEE/SICE International Symposium on System Integration 2018-January 巻 ( ThA1.3 ) 頁： 188 - 193 2017年12月

This paper presents a measuring position determination method of Unmanned Aerial Vehicles (UAVs) for automatic visual inspection. Ensuring accuracy and considering efficiency of operations in data gathering to detect anomaly are both important functions for inspections. This method is under the assumption that the 3D model of a target facility, required accuracy of gathering data and specs of instruments are given. The triangular polygons for shape description of the 3D model are reconstructed to those for measurement and the measuring positions; the waypoints that an UAV travels to gather the accurate data of the target facility efficiently are calculated systematically. If the measuring positions are obtained, the flight path appropriating for visual inspection can be planned by general path-planning methods by setting the measuring positions as waypoints. For evaluation of efficiency of measurement, the proposed method is examined through computer simulations on the assumption that an UAV measure image data of two typical bridges; a girder bridge and an arch bridge.
